Bulgarian Fatherland Front

The Bulgarian Fatherland Front (OF) was an anti-fascist popular front founded in the Tsardom of Bulgaria in 1942. The OF carried out a coup d'etat in Bulgaria in 1944 when the Soviet Union declared war on Bulgaria and began to invade the Balkans, and the OF allied Bulgaria with the USSR during World War II. The OF would continue to be a political alliance until the fall of communism in 1989.
